► Summer resurfacing projects are planned for the Bar Barry Heights Neighborhood and the Chauncey Village area. More specific information will be provided when it becomes available.

► The Klondike Road project continues with the Phase One road closure of the intersection of Klondike and Lindberg roads and Klondike Road north from Indiana 26 to the KB&S rail crossing. Detour information is available on the project website at ReviveKlondike.com. The roundabout at Klondike and Lindberg is scheduled to open in June.

► County Road 450/430 South between Newcastle Road and U.S. 52 will close on May 10 until about Oct. 10 (180 days) for new road construction. This reconstruction project began recently with utility relocation. The project eliminates the two 90-degree turns and provides appropriate access to future industrial sites to the east.

To complete the project in one construction season and open prior to the beginning of the school year in August, both Concord Road and County Road 430 South will have to be closed. County Road 430 South will close on May 29 and Concord Road on June 3.

► The expected start for the North Ninth Street Road project from Burnetts Road to Prophet Street in Battle Ground is July 8. Construction will require a full road closure; however, the project should only take about 20 days.

Once completed the contractor will move to County Road 900 East then to County Road 500 East and the railroad. Only one bridge will be closed at a time for up to 30 days. There will be county road detours posted for each closure.

► INDOT continues its work to replace the Indiana 26 bridge over the Wildcat Creek. A temporary traffic light regulates the alternating one-lane flow of traffic. Expect delays at the construction site until late in 2019.

► INDOT is patching and resurfacing Indiana 26 from one mile east of I-65 to just east of U.S. 421. The contractor will impose a rolling one-lane closure of the road but only in the area where work is occurring.
